IPv4协议最终将被IPv6协议所取代，但目前基于IPv6协议的应用研究还处于初始阶段。本文分析了FTP协议对IPv6 协议的支持情况，提出了一种Linux环境下基于IPv6协议的FTP 服务器实现方案。对实现的FTP服务器进行了测试，利用Sniffer软件进行了抓包分析。实验表明，该FTP 服务器完全支持IPv6 协议,并能实现用户登录、密码验证、文件列表传送、文件下载、文件上传、文件删除等功能。

It is well known that IPv4 will eventually be replaced by IPv6. However,the current development of network applications based on IPv6 is still in the initial stage. The paper analyzes the support of FTP for IPv6,and proposes a solution for the FTP server based on IPv6 in Linux. The FTP server is tested in real networks and the working process is analyzed with the Sniffer software. The result shows that the proposed FTP server fully supports IPv6,and the basic functions such as login,authentication of passwords,sending of file lists,downloading,uploading and deleting of files are implemented.
